Outline of Final Research Achievements

We investigated “magnetic reconnection” phenomena and their related energy transfer process with Hinode observations and discovered a precursory structure of sunspot penumbra during the development of sunspots. We also identified high-speed gas flows at the photosphere excited in horizontal magnetic field and their key roles on the development of energy for leading to an energetic flare. In addition, we established concepts on high-speed CMOS camera and high-throughput UV spectroscopic telescope, both of which are essential in next-generation observations. The SOLAR-C mission proposal, which includes results from our conceptual studies, has been submitted to JAXA.
